SPECIFICATION formingpart bf r.ettrs Patent No. 608,567, dated August 9, 1898. Application filed MartilrLlSQ'Z. Serial I l 'o. 62 5,654. (N0 model.)

a citizen of the United States, residing; in Gincinnati, in the county of Hamilton'andState of Ohio, have invented a new and useful Improvement in Automatic Sack 'Filling and Sewing Machines, of which the following isa specification. I My invention relates to improvements "in sack filling and sewing machines. I The object of my invention is to provide an automatic machine of a simple, durable; and efficient construction, of a compact form,soit' will occupy little space inthe warehouse or mill, and by means of whichfi'sacks' orbags may be cheaply; and" rapidly filled andthe filledsacks sewed-and discharged from the machine.

The machine embodyingmy invention comprises an intermittently-revolubleI'carrierj or turn-table uponwhich are/mounted a series of opening and closing sack-holders,'the same being preferably four ini numbenso'that a" sack may be placed in one holder while the sack in another holder is'bei ng filled, thatrin another sewed, and that in thelreinaining holder released or discharged, all simultaneously; a sewing mechanism mounted upon a reciprocating carriage and. operating to sew the filled sack in one of the holders; a'sa'ckfilling mechanism or spout for deliveringthe material into the sack; a shaker. or device for compacting the material in the sack; mechanism for automatically opening the holders at suitable intervals and locking them open; mechanism for automatically closing the holders and locking them closed at suitable intervals; and mechanism for automatically imparting a step-by-step movement to the holder-carrier and looking it in position for the several holders thereon to properly registeuand cooperate with the other de part of this specification, and in which similar letters of reference indicate like parts in all the views, Figures 1 and 1*, taken to gether, are a side elevation of a machine embodying my invention. Fig. 2 is aplan view. Fig. 3 is a section on the line 3 3 of Fig. 2, showing the sewing device. Fig. 4 is a bottom plan view of the sewing device. Fig. 5 isa section on'the line 5 5 of Fig. 3. Fig. 6 is a detail view of the shifting-gear for throwingthe sewing mechanism in and out of gear. Fig. 7' is 'a detail side view of. the shaker. Fig. 8 is a section on the lineS 8 of Fig. 7. Fig. 9 is a detail end view of parts herein after to be described. ,FigrlO "is' a detail plan view of one of theholders and mechanism for-flocking it closed. Fig. 11 is a section on the line 11 11 of Fig. 10. Fig. 12 is'an enlarged side elevation of thesewing'mechanism. Fig. 13 is an enlarged planview of the sewing mechanism," and Fig. 141s a detail perspective view of the mutilated gears.

In the drawings, A represents the frame of themachine. Y Y a vB is the intermittently-movable carrier, upon which the sack-holders are mounted, the same being preferably in the form of a revolving wheel or tur'n-tablei sufficiently large in diameter to enable four sacks to be simultaneously suspended from it. The carrier B is provided with four openings B, over or adjacent to which the sack-holders are located, said openings being preferably of a diamond shape.

;. B is the pedestal or support, upon which the carrier Brotates, and B .is the shaft, to which the carrier is secured and which is journaled in said pedestal.

1C 0 are bars secured at their outer'ends to the frame and supported at their inner ends bythe upper end of the shaft 13 which is extended up through the carrier for this purpose. The bars 0 G are located abovethe carrier and are furnished with pins or.-projections c to open and c to close the holders and their locking devices as the same pass under these bars in; the rotary movement of the carrier. I

D D are the opening and closingsa'ck-holders, the same consisting, preferably, each of four bars cl (1, hinged together at their meet- IOO ing ends by pivots (Z and (Z and provided with suitable sack-holding hooks or devices (Z for suspending the sack therefrom. Each of the holders D or its two end pivots (1 (1 is adapted to reciprocate in guide-slots b b in the carrier B as the holder opens and closes, and the two middle pivots (Z d of the holder are connected to two reciprocating slides l) I), mounted to reciprocate radially in or on suitable guides b b on the carrier I The slides 11 are provided with notches N, which are engaged by pawls or latches l), pivoted on the carrier, and which serve to lock the holder in its open position, and the slides Z) are also furnished with notches I), that are engaged by the same pawls, so as to lock the holder in its closed position. The pawls II are furnished with springs b", that serve to throw them into engagement with said notches and to hold them in such engagement. The pawls are also provided with suitable pins or projections U, which engage suitable pins or projections c e on the arm 0 to retract the pawls, and thus permit the holder D to open. The holder D is opened automatically when the pawls are retracted by coiled springs d, with which the holders are provided. The holders are automatically closed by cams, inclines, or projections (1, with which theholders are provided, engaging pins, projections, or rollers c c on the arm 0.

E is the filling device.

The filling device may be of any suitable construction. As illustrated in the drawings it consists of a spout or hopper located above the holder-carrier.

F is the shaker or device for settling or compacting the material in the bag as it is filled. It may be of any suitable construction. As illustrated in the drawings it consists, essentially, of an up-and-down vibrating table adapted to lift the bag on its upward movement and drop it suddenly on its downward movement, so as to settle and compact the material therein. The shaker F is thus vibrated or moved up and down by means of two eccentrics F 011 the shaft F which revolve in blocks F, that slide in yokes F,pivoted to the frame, and upon which sliding blocks the shaker F rests. By this means the sack is given not only an up-and-down movement, but a slight lateral movement, which aids in settling and compacting the material in the sack.

G is a reciprocating or traveling carriage upon which the sewingmechanism is mounted and by which the sewing mechanism is moved or fed forward from one end of the seam to be formed in the sack to the other. This sewing-carriage G slides upon suitable guides G G, secured to the frame of the machine above the carrier 13. The sewing-carriage G is reciprocated or moved back and forth along said guides by a revolving screw G which engages or revolves in a nut G", attached to the carriage G. Mounted in a dovetail guide in the sewing-carriage G is a reciprocating slide g, by which the looper II and needle K are operated. The slide 1 is reciprocated back and forth on the carriage G by means of a vibrating rod g, that en gages pins or projections on the slide g, and which rod is secured to arms on the rock-shaft g". The rock-shaft g" is caused to rock by being furnished with an arm 1 having a slot q", in which travels a sliding block through which is inserted a crank 1 journaled loosely on the end of the screw 1 The crank g is furnished with a pivoted pawl g, which engages a ratchet that locks the crank to the screw-shaft when the screw-shat" t is turned in one direction, and thus causes the shaft to rock, while permitting the screwshaft to turn in the opposite direction. without turning the crank. A spring holds the pawl in engagement with the ratchet. By this mechanism it will be seen that the needle-operating slide 9 will be actuated or reciprocated by the revolution of the screwshaft itself when the screw is being rotated in one direction and that it will be out of gear with the screw-shaft when said screw-shaft is turned in the other direction. The screwshaft G2 is rotated first in one direction and then in the opposite direction to cause the sewing-carriage G to travel back and forth, as required. The rotation of the screw-shaft is automatically reversed when the sewingcarriage reaches the end of its travel in either direction by means of a sliding sleeve G, furnished with two gears G G, adapted to engage the driving-gear N, the one or the other. This sleeve is splined to the screwshaft, so as to rotate with it, and it is reciprocated on the screw-shaft to throw one of its gears into and the other out of engagement with the driving-gear by means of a slide G" on the rock-shaft g, which is furnished with arms G adapted to be engaged by the sowing-carriage G when it reaches the limit of its movement at either end.

The looper It is provided with an eye or hole 71 near its end, through which the thread passes, so that the looper may by its vibratory movement at intervals, as required, press the thread against the needle K and into the recess, slit, or notch with which the needle is provided. The looper II is secured to or made integral with a vibrating arm II, which is secured to or made integral with a rockshaft H journaled in suitable bearings .ll on the sewing-carriage G. This rock-shaft II is hollow or in the form of a sleeve, and it is provided at its rear end with an enlarged or collar portion II", which is provided with a spiral groove or cam 71/, that is engaged by a pin 71?, fixed to a sleeve h reciprocating inside the sleeve or rock-shaft 11 so that a vibratory or swinging movement may be communicated to the looper ll and its operatingarm and rock-shaft by the reciprocation of the sleeve 703 inside the sleeve Il The reciprocating sleeve h is provided with a longitudinal slot 7t and with an adjustable collar or stop it andrisitself reciprocatedby a pin 7L6 onthe slide or arm 71*, which lS COl1- slotted sleeve 7L3 backward or forward thelooper, may be made to pause a shorter or longer interval in positionto hold the thread against the needle K, as required.

The needle K is provided with a slot or hook to receive the thread, and the lip 7i) of the hook is depressed below or within the general surface of the needle back of the lip, so that the edge or point of the lip will not catch upon the fabric or interfere with the withdrawal of the needle from the fabric, while at the same time serving to uniformly and securely catch the thread whenthe thread is pressed by the looper into the bevel or recess 70 just .back of the lip. The needle K is secured ina hinged or yielding needle-holder K, pivoted to the needle-operating slide g at K sothat the needle may have a slight tilt ing or yielding movement to prevent lateral strain thereon and compensate for the continuous forward movement of the sewing-carriage G in respect to the stationary sack X, held in the holder D. A torsional spring K secured to-the needle-operating slide 9 and bearing -against the needle-holder K, serves to return the needle-holder K into a straight line with or parallel to the needle-operating slide g after the needle is withdrawn from the sack The filling device Eis provided with a cutoff'slide orvalve E below the hopper E and a similar valve or slide E above the hopper, which slides or, valves are operated simultaneouslyj by a common lever E to which the slides are connected by pivoted links E The hopperfE should be made of a size corresponding to that of the sack to be filled, so as thus to measure the material into each sack.

E is the delivery-spout, by which the material to' be sacked is delivered first into the hopper E and thenthrough the filling-spout 7 Acontinuous rotary mot-ion is communicated V to thiscounter-shaft N from the drivingshaft M through suitable connecting gearin g. I

The connecting-,gearin g may preferably consist of a beltM running 011 the pulley M on the drivin -shaft Maud over. a pulley P on the counter-shaft P, which is furnished with a gear P that meshes with, a gear N on a counter-shaft N which is provided with a bevel-gear N, that meshes with a bevelgear N on the counter-shaft'N, which has a bevelgear N meshing with a bevel-gear N 8 on the lower end of the upright counter-shaft N.

The necessaryintermittent or step-by-step rotary movement may be communicated to the sack-holder carrier B from the drivingshaftand the carrier intermittently locked stationary and in position for the holders D D D D, mounted thereon, to register one with the sack fillingand shaking mechanisms, one with the sack-sewing device, one at the filled and sewed sack discharging station or discharge-chute R, and one at the station where the sacks are inserted in the open holder by any suitable connecting gearing or mechanism. The mechanism which I prefer to employ, however, for so intermittently revolving and locking the holder-carrier B in position consists in a mutilated gear 13, secured lated gear 13 is furnished with locking pro- 'ections B which en a e the smooth locking- J 9 O D face P of the mutilated gearP and thus posiv tively lock the carrier B in position.

The sewing-carriage G is preferably provided with guides G G between which the mouth or upper edges of the sack pass to hold the same inposition while the needle is being thrust through and withdrawnfrom the same. These guides act as presser-feet and are fur.- nished with holes or perforations for the needles topass through.
